NOTGH-GHAMFERING MACHINE FOR MATRICES.

Application filed January 16, 1907.

T all whom "it may concern.

. 3e it known that 1. Holmes A. ltm'ivoluns, residing at ll'oonsocket,in the county of Providence and State of Rhode Island, have invented acertain new and useful Improvement in Noteh-Ohamfering Machines forMatrices, of which the following is a full, clear, and exactdescription.

In certain kinds of matrices, adapted for use in linotyping machines,there is a \l-shaped alinement notch in one of the vertical edgesthereof. It is necessary that, after these V-shaped notches have beenformed, their edges should be slightly beveled or chamfered for thepurpose of eliminating sharp corners and bars, and of making said edgesabsolutely smooth.

The object of this invention is to provide a machine adapted for quicklyand accurately beveling the edges of these V-shaped notches in matricesof various thicknesses.

In the drawing, Figure l is a plan view of a machine embodying myinvention. Fig. 2 is a front view thereof with a portion of the bedplate broken away. Fig. 3 is a vertical sectional view through the lowerpartof the receiving magazine and adjacent parts. Fig. 4 a sectionalelevation in the plane of line H of Fig. 1. Fig. 5 is a perspective viewof a spring actuated stop plate. Fig. 6 is a sectional elevation in theplane of line G-G of Fig. 1. Fig. T is an enlarged plan view, partlybroken away, of the slide and its guide way. Fig. 8 is a sectionalelevation of that part of the machine which is shown in Fig. 7,thesection being taken in the plane indicated by line SS of Fig. 7. Fig. 9is a side view of a matrix after it has been acted upon by the machine;and Fig. 10 is an ent larged sectional view in the plane of line 101O onFig. 9.

A represents the bed plate of the machine in which are two channels a a,which are at right angles to each other, and which are connected withone another as shown,the bottom of these channels being in the samehorizontal plane. The width of the channel a is substantially equal tothe height of the matrix; while the width of the channel a issubstantially equal to the width of a matrix.

A feed magazine B is supported above the channel a,this magazine beingof such size that the matrices Y, lying on their sides, fit looselytherein. A pile of these matrices to be operated upon is put into thismagazine Specification of Letters Patent.

and the bottom matrix rests upon the bottom of the channel a. The bottomof the magazinc is elevated above the bottom of the channel a distanceslightly greater than the thickness of a matrix and not as great as thethickness of two matrices, so that the bottom matrix, and that only maybe pushed out of the magazine along that channel.

The receiving magazine D is secured over the channel a. with one loweredge at such elevation that a matrix may pass under it.

A vertically movable presser foot F extends over the two channels a, abetween these two magazines. Its vertical stem f is mounted in thestandard E; and this presser foot is subject to the influence of aspring f pressing it downward. A lever H is pivoted to this standard,and has a horizontal arm, shown in dotted lines in Fig. 2, which entersa recess in the prcsser foot stem, wherefore by operating this lever thepresser foot may be temporarily raised. There is a set screw 0 whichscrews through the standard E and engages with the upper arm ,of thelover H, and thereby limits the downward spring-induced movement of thepresser foot.

In the two channels a and a, respectively, the slides G and J areplaced. These slides are respectively connected, in a well known manner,with the arms m, m, of a lever which is pivoted upon the bed A and isprovided with an operating handle M. Slots m in these levers receivepins 9, j, which are fastened to said slides. It is evident, therefore,that by operating the handle, these two lever arms will be rocked andthe two slides will be moved along in the channels in which they lie.Two set screws 0, 0 lie in the path of the handle of the lever M, andthereby limit its movement in both directions.

A vertically movable block K has arms which serve as bearings for ashaft P, which carries a driving pulley pand a milling cutter Q having aV-shaped cutting edge. This block K is adj ustably mounted upon astandard S, and is raised and lowered, so as to bring it at the desiredelevation for matrices of ditterent thicknesses by means of a screw 8rotatively mounted in a flange 8 upon said standard S and screwiu g intothe block K, said screw being prevented from moving endwise in thestandard. This standard is also adjustable sidewise upon the bed plateA, and its position accurately determined by the set screws 8 s. Asuitable belt (not llO shown) is to drive shaft P and the cutter Q,secured thereto.

In operating the machine, a pile of matrices Y, to be operated upon, areplaced in the magazine B lying upon their sides. An operator swingslever hf into contact with the stop screw 0. As it moves to thisposition, slide J is moved to the right, as shown in Fig. l, and thispushes the lowest matrix, of the pile in magazine B, along into thechannel a until the end of said matrix comes into contact with the rightside wall of the channel a. Likewise this matrix passes under thepresser foot F. The lever M is now swung in the contrary direction intocontact with adjustable stop 0, thereby moving the slide G rearward. Therear end of this slide engages with the matrix referred to and pushes itrearward into engagement with the milling cutter. This cutter is placedin such position and is of such shape that it engages with the edge ofthe V-shaped slot and bevels off a very small part of the cornersthereof on one side, as shown in Figs. 9 and 10. The engagement of thelever M with the stop screw 0 determines the exact distance which saidmatrix shall be moved, and therefore it determines how much of thecorners shall be so beveled off.

The levers R are pivoted to the slide G near the sides thereof, and theyproject rearward beyond the end of said slide, and each has an up-turnedfinger r. These levers are below the slide and lie in a recess a in thebed plate, especially provided for them. In the sides of this recess aretwo horizontal guide grooves a (4 located one above the other. Each ofthe grooves a at its front end, is curved downward and merged into thegroove a while, at the rear end of these grooves, the separatingpartition a is cut away, so that they are thereby connected. Each ofthese levers F. has a pin T which projects laterally into these grooves.When the slide G is moving rearward, pins r are in the lower grooves cand therefore the fingers r are held below the bottom of the channel a.l/Vhen slide G is moving forward, these levers are brought into contactwith the fiat springs T, wherefore the levers are given an upwardimpulse. When the pins 7 are carried beyond the end of the partition (6,these levers are moved up by said spring, which brings the fingers 7"just behind the matrix which has just been operated upon. IV hen, now,the slide G moves forward, these fingers engaging with said matrix drawit forward until it is brought beneath the receiving magazine D. Vhenthe slide G is so moving forward, the slide J is moved to the right,carrying another matrix from magazine B into position before described;and the end of this matrix passes beneath the presser foot F before thefirst matrix is drawn from beneath the same.

In the bed plate directly below magazine D is a plunger W provided witha spring w, wherewith it is drawn downward. At tached to this plungerare four pins w which pass up through holes in the bed plate, andparticularly through the bottom of the channel (4. Normally these pinsdo not ex tend above the bottom of said channel. In the plunger IV thereis a notch 10 which receives one end of a pivoted lever Z. The other endof this lever is provided with a beveled surface a which projects upinto the path of the slide G. lVhen this slide is moved forward farenough to carry a matrix beneath the magazine D it is, of course, passedover the pins '10. This slide then strikes the beveled surface 2,thereby rocking lever Z. This results in lifting the plunger IV, wherebythe pins to push the matrix upward. In so moving the ends of the matrixengage with the beveled lower surfaces of spring-actuated fingers Uwhich project a very short distance into the magazine D from the sidesthereof. These fingers are se cured to the lower ends of yieldingsprings a whereby when the matrix is pressed upward these fingers arepushed outward and the matrix passes them. These fingers immediatelyspring inward beneath the matrix, and thereby sustain it and all of theother matrices above it.

Adjacent to the front side of the magazine D is a stop plate V which hasan upwardly extended guide stem o. A spring 1) presses this stemdownward so as to hold the plate V down on top of slide G. When,therefore, the slide G is moved forward to carry a matrix beneaththemagazine D, this plate by bearing upon the top of the slide will bein the path of the matrix and will stop it in the desired positionbeneath the magazine. At the same time the pins 1" will be drawndownward by the downwardly bent front end of the groove a so that thefingers 1" will be below the bottom of the matrix wherefore the matrixmay remain in position in which it will be stopped by said plate V asthe slide G continues its forward movement. The front edge of this plateV is beveled so that when the slide G moves rearward again the plate islifted.

The described operations are carried on indefinitely until all of thematrices in the magazine B have been moved therefrom and subjected tothe action of the cutter Q; and are delivered into the magazine D.

This machine is adapted to be used with matrices of differentthicknesses. It is for this reason that the block K and the partssupported thereby are made vertically adjustable.
